SUMMARY:Gabriela Weitze-Schmithüsen (Universität des Saarlandes\, Saarbr
 ücken (Germany)): Systoles sur les origamis
DESCRIPTION:Gabriela Weitze-Schmithüsen: Although translation surfaces hav
 e been intensively studied since the 1980’s\, there are still many natur
 al questions wildly open.\nOne of these questions is: what is the maximal 
 systolic ratio in a stratum\, i.e. what is the maximal length of a shortes
 t simple closed geodesic on a translation surface of area 1 in a fixed str
 atum? We study this question of translation surfaces of genus 2 with two s
 ingularities.\nThis is joint work with Colombus\, Herrlich\, Mützel.\n\nh
 ttps://arxiv.org/abs/1809.10327\n\n&nbsp\;\n\n\n\n\n\n\n\n\n\nAn origami O
  with 30 squares whose systole is √17. O has two singularities • and 
 ◦.\nThe dashed line is a systole (arxiv.org/abs/1910.0845\, fig.4\, page
  23)\n\n\n\n\n\nParticiper à la réunion Zoom:\n\nhttps://univ-amu-fr.zoo
